The latest development in the aftermath of the attacks on Brussels Airport and Maalbeek metro station: an employee of on of Belgium’s nuclear plants was found dead with his work pass stolen. The discovery was made Friday but only appeared in Belgian papers this morning.

Last year, there were incidents at Belgian nuclear power plants which were linked to possible sabotage. After the Paris attacks, Belgian media discussed the likelyhood of the terrorists being interested in producing so-called dirty-bombs.

Security was steppend up and – as in France – several employees had their work passes revoked. Some of the terrorist involved in the recent attacks in Brussels, were actively involved in a surveillance of a senior nuclear official. They may have been planning an abduction or other means of access to plants.

Security at nuclear plants in Belgium and France was increased after the recent attacks. According to the UK Telegraph: “In the hours following the Brussels bombings, two Belgian nuclear power plants were evacuated.”

It is unclear if security at the nuclear power plant in the Netherlands, not far from the Belgian Doel ones, has also been increased. If anything should go wrong at any of these sites, large parts of Belgium and the Netherlands would be affected.
